Solar Impulse team (flying across the USA in a solar plane) doing Q&A on Reddit

Flying across the USA in a solar plane We've written about the Solar Impulse solar plane a few times . It's not only a great feat of engineering, but it's also a project that follows in the footsteps of a long tradition of pioneers and explorers who attempted things that nobody else had done before.The current challenge: From May to July, Solar Impulse will cross the United States without using a single drop of fuel . The crossing will happen in several stages: it will take off from San Francisco and stop in four US cities, including Washington DC, before reaching its final destination: New York City. To discuss the project and answer people's questions, the Solar Impuse team is doing a Q&A on Reddit (proof ). Check it out: Solar Impulse Ask Me Anything .
